So this is where I got really picky. I wanted 2 monitors: a 2K 144HZ monitor for gaming, and a 4K 60HZ monitor for productivity. Obviously they needed to have Freesync and they needed to be VESA compatible, but most importantly, they needed to have the same physical exterior. So I settled for the Acer VG270U and Acer VG270K. I bet you can't tell the difference between them (left is 2K, right is 4K).
